ASB Bank Tech Stack

New Zealand bank modernizing legacy systems and lending platforms

Banking Auckland 1,001–5,000 employees Founded 1847 Public Company

ASB Bank is a 1,000+ person public bank headquartered in Auckland, running a tech modernization spanning lending, core systems, and CRM infrastructure. The stack reflects a hybrid enterprise maturity: SAP S/4HANA + Pega for banking operations, Azure cloud infrastructure, and data analytics (Snowflake, Databricks, Tableau). Active replacement of Windows Communication Foundation signals a broader legacy services rewrite, while hiring velocity is accelerating—particularly in engineering (48 open roles) and finance—indicating sustained investment in transformation programs rather than maintenance-mode operations.
